| Abstract |
The author describes fourteen species and subspecies of the genusBrachyspirifer WEDEKIND, R., 1926 collected in the Siegenian, Emsianand Couvinian formations of the southern side of the Dinant synclinorium.Three species, B. minatus n. sp., B. mixtus n. sp. et B. niger n. sp. are new;five others are provisionally designed B. cf. crassicosta crassicosta,B. groupe crassicosta, B. cf. sphaeroides, B. cf. carinatus rhenanus and B.cf. ignoratus. A biostratigraphic zonation based on the vertical extensionof those species and subspecies is proposed and compared with that usedin the « Rhenische Schiefergebirge ». |
